Standard Urban Stormwater Mitigation

Stormwater Urban Mitigation Plan (SUSMP) requirements only apply to
projects that have received Prior Lawful Approval (PLA) before
February 26, 2016. Projects without PLA on or after February 26, 2016
will be subject to the requirements of the County
BMP Design Manual.

The SUSMP is intended to help implement one part of the County's
Stormwater Program. The SUSMP only addresses land development and
capital improvement projects. It is focused on project design
requirements and related post-construction requirements, not on the
construction process itself.
